Chemistry density lab answers
Use the metric ruler provided in your lab kit to make linear measurements (measurement of length). Density. Density is an important property of matter because the density does not depend on the amount of a substance. For example, 1 drop of water has the same density as 1 liter of water.Density is the amount of matter in an object compared to its volume (the amount of space it takes up). If an object were extremely dense, it would feel heavier than another object of the same size that was less dense. For example, a 1-litre soda bottle filled with air would feel much lighter than the same bottle filled with water. Water has a density of 1 kilogram per liter, while air has a ...Density Sweet Density. Calculate densities of candy bars and predict what will happen when they are placed in water.
